The Australian navy is reporting that it has found the missing U.S. military aircraft, which crashed off of the Australian coast. Three marines had been missing after the crash, which happened Saturday. There were 21 passengers and five crew members on board the tilt-rotor aircraft when it went into the water. The U.S. military says the plane was on final approach to the U.S.S. Green Bay when it hit the flight deck and crashed. All but three aboard were rescued. The military says the cause of the crash is under investigation.
